single_pipe_vin_isp_ynr_pym_vpu​

功能概述​

single_pipe_vin_isp_ynr_pym_vpu 示例串联 VIN，ISP，PYM，CODEC 模块，是最基础的模块串联示例之一。 Camera Sensor 图像经过 VIN、 ISP 处理后到达 PYM 模块， PYM 模块配置了六个输出通道功能分别如下：

  • 0 通道输出 ISP 和 YNR 处理后的原尺寸图像，本通道的输出数据会再送给编码器编码后保存为 H264 视频码流。
  • 1 通道输出 16 像素对齐、宽和高各缩小 2 倍、 NV12 格式的图像
  • 2 通道输出 16 像素对齐、宽和高各缩小 4 倍、 NV12 格式的图像
  • 3 通道输出 16 像素对齐、宽和高各缩小 8 倍、 NV12 格式的图像
  • 4 通道输出 16 像素对齐、宽和高各缩小 16 倍、 NV12 格式的图像
  • 5 通道输出 16 像素对齐、宽和高各缩小 32 倍、 NV12 格式的图像

注意： PYM 输出的最小分辨率为 32 ，如果缩放后的宽或高小于 32 ，就不会保存图像

multi_pipe_vin_isp_ynr_pym_gdc_vpu​

功能概述​

multi_pipe_vin_isp_ynr_pym_gdc_vpu 支持同时接入多路 Sensor 输入，并通过 VIN、 ISP、 PYM、 GDC、 CODEC 等多个处理模块进行视频流处理

注意：

  1. GDC 模块依赖 bin 文件作为输入，本示例程序从目录 /app/multimedia_samples/vp_sensors/gdc_bin 中搜索 bin 文件，找到合适的 bin 文件才会运行 GDC 模块
  2. CODEC 模块输入的宽和高最小分别为 256 和 128 ，所以当选择 PYM 的通道输出分辨率小于 CODEC 模块的最小宽和高时，程序会直接退出
